Description

Technical Field

[0001] This application relates to the field of power supply and distribution technology, and in particular to an integrated wind power, photovoltaic, and energy storage power distribution access device. Background Technology

[0002] With the continuous development of new energy technologies, photovoltaic power generation and wind power generation have gradually become important components of the power supply system due to their clean and renewable characteristics. Photovoltaic power generation converts solar energy into electrical energy through photovoltaic modules, while wind power generation converts wind energy into electrical energy through wind power generation equipment. Both can be used as new energy power supply methods in different scenarios.

[0003] In related technologies, photovoltaic (PV) power generation equipment and wind power generation equipment are typically equipped with independent power supply access structures to separately realize the access and output of PV power and wind power. In some application scenarios, it is also necessary to configure corresponding power distribution units, line structures, and installation spaces for PV power generation equipment and wind power generation equipment respectively to complete their respective power supply deployments.

[0004] However, in the above setup, the photovoltaic power generation equipment and the wind power generation equipment are arranged independently, which results in a large overall footprint and low space utilization. At the same time, the dispersed setting of different power supply structures is not conducive to unified wiring, centralized maintenance and overall management, which in turn affects the convenience of equipment use and the system integration.

Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this specification as detailed in the appended claims.

[0051] The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” as used in this specification and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0052] In related technologies, photovoltaic power generation equipment and wind power generation equipment are usually set up independently and supply power to each other, resulting in a large overall equipment footprint, low space utilization, and the decentralized layout is not conducive to unified wiring, centralized maintenance and centralized management, thus affecting the system integration and the convenience of use and maintenance.

[0053] Based on this, this application provides an integrated wind power, photovoltaic, and energy storage power distribution access device, see [link to relevant documentation]. Figure 1 , Figure 2The integrated wind power, photovoltaic, and energy storage power distribution and access device includes a power distribution housing 1, an energy storage mechanism 2, a wind power access mechanism 3, a photovoltaic access mechanism 4, and a heat dissipation mechanism 5. The power distribution housing 1 has a cavity. The energy storage mechanism 2 is located inside the power distribution housing 1 and has a first interface 21, a second interface 22, and an output port 23. The wind power access mechanism 3 is located inside the power distribution housing 1 and is electrically connected to the first interface 21 to connect wind power to the energy storage mechanism 2. The photovoltaic access mechanism 4 is located inside the power distribution housing 1 and is electrically connected to the second interface 22 to connect photovoltaic power to the energy storage mechanism 2. The output port 23 is used to connect to an external power distribution side so that the energy storage mechanism 2 can distribute power to the outside. The heat dissipation mechanism 5 is located inside the power distribution housing 1 and is used to dissipate heat from at least one of the wind power access mechanism 3 and the photovoltaic access mechanism 4.

[0054] In this embodiment, the wind power access mechanism 3 connects wind power to the energy storage mechanism 2 via the first interface 21, and the photovoltaic access mechanism 4 connects photovoltaic power to the energy storage mechanism 2 via the second interface 22. The energy storage mechanism 2 stores the connected power and distributes it to the external power distribution side through the output port 23. During the operation of the wind power access mechanism 3 and the photovoltaic access mechanism 4, the heat dissipation mechanism 5 dissipates heat from at least one of them. Compared with the separate installation and power supply of photovoltaic power generation equipment and wind power generation equipment in related technologies, this application integrates the wind power access mechanism 3, the photovoltaic access mechanism 4 and the energy storage mechanism 2 into the same power distribution housing 1, which is beneficial to reducing the overall footprint, improving space utilization, and enabling unified wiring, centralized maintenance and unified management. At the same time, by setting up the heat dissipation mechanism 5 to dissipate heat from the corresponding heat-generating components, it is also beneficial to improve the operational stability of the device.

[0055] Understandably, at certain times, the efficiency of either the photovoltaic access mechanism 4 or the wind power access mechanism 3 may be lower, resulting in lower heat generation requirements. The heat dissipation mechanism 5 can selectively dissipate heat from either the wind power access mechanism 3 or the photovoltaic access mechanism 4, thereby avoiding unnecessary heat dissipation from the other mechanism and reducing energy consumption during the heat dissipation process.

[0056] In some embodiments of this disclosure, see Figure 1 , Figure 2The power distribution access device includes multiple partitions 11. These partitions 11 divide the cavity of the power distribution housing 1 into multiple sub-chambers, where the wind power access mechanism 3, photovoltaic access mechanism 4, heat dissipation mechanism 5, and energy storage mechanism 2 are respectively located. By dividing the different functional mechanisms into multiple sub-chambers, the wind power access area, photovoltaic access area, heat dissipation area, and energy storage area can be relatively independent of each other, thus forming a clearer internal layout structure. During equipment use, different mechanisms can complete access, energy storage, and heat dissipation work respectively in their corresponding sub-chambers. This also helps improve the neatness and clear zoning of the internal layout of the power distribution housing 1, facilitating installation and wiring organization. Furthermore, the relatively independent setting of different mechanisms helps reduce interference with other mechanisms during the inspection or maintenance of one mechanism, facilitating individual inspection, daily maintenance, and centralized management, thereby improving the convenience of use and maintenance efficiency of the device.

[0057] In some embodiments of this disclosure, see Figure 2 Along the first direction, the wind power access mechanism 3 and the photovoltaic access mechanism 4 are respectively arranged on both sides of the energy storage mechanism 2, and the heat dissipation mechanism 5 is located on the same straight line as the energy storage mechanism 2. The first direction is perpendicular to the width direction of the power distribution housing 1. By arranging the wind power access mechanism 3, the energy storage mechanism 2, and the photovoltaic access mechanism 4 along the first direction, the wind power access mechanism 3 and the photovoltaic access mechanism 4 can be arranged to extend outwards from the energy storage mechanism 2 to both sides. At the same time, the heat dissipation mechanism 5 is arranged corresponding to the energy storage mechanism 2 along the first direction, so that the heat dissipation mechanism 5 can deliver heat dissipation airflow or perform heat dissipation function to the area where the energy storage mechanism 2 is located along a relatively direct path when working.

[0058] By placing the wind power access mechanism 3 and the photovoltaic access mechanism 4 on opposite sides of the energy storage mechanism 2, the length of the wiring between them is shortened, reducing circuitous routing and making the internal wiring simpler and more compact. Simultaneously, the heat dissipation mechanism 5 and the energy storage mechanism 2 are located on the same straight line, allowing the heat dissipation mechanism 5 to cool the energy storage mechanism 2 in a shorter time, thus improving the heat dissipation response efficiency of the energy storage mechanism 2. Since the energy storage mechanism 2 is typically in continuous operation and has a continuous need for heat dissipation, placing the heat dissipation mechanism 5 opposite to the energy storage mechanism 2 also prioritizes meeting the heat dissipation needs of the energy storage mechanism 2, thereby improving the stability of the device operation.

[0059] It is understandable that the working status of wind power access mechanism 3 and photovoltaic access mechanism 4 may differ at different operating times. However, energy storage mechanism 2 usually participates in the energy storage and distribution process continuously. Therefore, compared with wind power access mechanism 3 and photovoltaic access mechanism 4, energy storage mechanism 2 has a higher requirement for heat dissipation timeliness. By placing heat dissipation mechanism 5 and energy storage mechanism 2 on the same straight line, it is also possible to better adapt to the heat dissipation requirements of energy storage mechanism 2 at most operating times.

[0060] In some embodiments of this disclosure, see Figure 2 , Figure 3 and Figure 4 The heat dissipation mechanism 5 includes a heat dissipation motor 51, a heat dissipation fan 52, a heat dissipation housing 53, and a heat dissipation channel 54. The heat dissipation housing 53 has a first air inlet 531. The heat dissipation housing 53 is located in the sub-chamber where the heat dissipation mechanism 5 is located. The heat dissipation motor 51 and the heat dissipation fan 52 are located inside the heat dissipation housing 53. The heat dissipation channel 54 is connected to the heat dissipation housing 53 and is connected to the other sub-chambers.

[0061] During operation, external airflow enters the heat dissipation housing 53 through the first air inlet 531. The heat dissipation motor 51 drives the heat dissipation fan 52 to rotate, thereby driving airflow. The airflow is then transported to the remaining sub-cavities through the heat dissipation channel 54 to dissipate heat to the corresponding areas of the wind power access mechanism 3, photovoltaic access mechanism 4, and energy storage mechanism 2. By setting up the heat dissipation housing 53, heat dissipation fan 52, and heat dissipation channel 54, a relatively concentrated heat dissipation airflow path can be formed, which facilitates the directional delivery of airflow to different sub-cavities. This is beneficial for improving the heat dissipation efficiency inside the power distribution housing 1, reducing heat accumulation, and improving the operational stability of each mechanism.

[0062] In some embodiments of this disclosure, see Figure 2 , Figure 3 and Figure 4 The heat dissipation channel 54 includes a first channel 541, a second channel 542, and a third channel 543. The first channel 541 is connected to the sub-chamber where the photovoltaic access mechanism 4 is located, the second channel 542 is connected to the sub-chamber where the wind power access mechanism 3 is located, and the third channel 543 is connected to the sub-chamber where the energy storage mechanism 2 is located. The length of the third channel 543 is less than the length of the first channel 541, and the length of the third channel 543 is less than the length of the second channel 542.

[0063] During operation, the cooling airflow generated within the heat dissipation housing 53 is transported via the first channel 541, the second channel 542, and the third channel 543 to the sub-cavities containing the photovoltaic access mechanism 4, the wind power access mechanism 3, and the energy storage mechanism 2, respectively, to dissipate heat in the corresponding areas. Since the length of the third channel 543 is shorter than that of the first channel 541 and the second channel 542, the cooling airflow has a shorter path and relatively less resistance during transmission through the third channel 543. This allows the sub-cavity containing the energy storage mechanism 2 to receive more cooling airflow, improving the heat dissipation effect on the energy storage mechanism 2. Because the energy storage mechanism 2 is typically in continuous operation and usually has higher heat dissipation requirements than the wind power access mechanism 3 and the photovoltaic access mechanism 4, making the third channel 543 shorter also helps to prioritize meeting the heat dissipation needs of the energy storage mechanism 2, thereby improving the operational stability of the power distribution access device.

[0064] In some embodiments of this disclosure, see Figure 2 , Figure 3 and Figure 4 The power distribution access device also includes a cut-off mechanism 6 and multiple temperature sensors 7. The cut-off mechanism 6 is located at the connection between the first channel 541 and the second channel 542 and the heat dissipation housing 53, and is used to cut off the transmission of heat dissipation airflow to the first channel 541 and the second channel 542; the multiple temperature sensors 7 are used to detect the operating temperature of the photovoltaic access mechanism 4 and the wind power access mechanism 3, and the cut-off mechanism 6 moves based on the operating temperature detected by each temperature sensor 7.

[0065] During operation, multiple temperature sensors 7 detect the operating temperatures of the photovoltaic access mechanism 4 and the wind power access mechanism 3, respectively, and feed back the corresponding temperature information to the shut-off mechanism 6. When one of the photovoltaic access mechanism 4 and the wind power access mechanism 3 has a lower operating temperature and a lower heat dissipation requirement, the shut-off mechanism 6 can move to the connection point with the corresponding channel to close the corresponding channel, thereby reducing the amount of heat dissipation airflow entering the corresponding sub-chamber. When the other of the photovoltaic access mechanism 4 and the wind power access mechanism 3 has a higher operating temperature and a higher heat dissipation requirement, the shut-off mechanism 6 remains offset from the corresponding channel to allow the heat dissipation airflow to continue to be transmitted to the corresponding sub-chamber, thereby dissipating heat from the corresponding mechanism. For example, on cloudy days or other times with weak sunlight, the workload of the photovoltaic access mechanism 4 may be lower, and the first channel 541 can be closed in this case; similarly, on days with low wind speeds, the workload of the wind power access mechanism 3 may be lower, and the second channel 542 can be closed in this case.

[0066] By incorporating a shut-off mechanism 6 and multiple temperature sensors 7, the power distribution access device can selectively shut down at least one of the first channel 541 and the second channel 542 based on the actual operating temperatures of the photovoltaic access mechanism 4 and the wind power access mechanism 3 at different times. This reduces unnecessary heat dissipation for mechanisms with lower heat dissipation requirements and allows more airflow to be directed to areas with higher heat dissipation requirements, thereby improving the targeting and response speed of localized heat dissipation. Simultaneously, this design also helps reduce the overall energy consumption of the heat dissipation mechanism 5 and improves the energy efficiency of the power distribution access device during operation.

[0067] In some embodiments of this disclosure, see Figure 2 , Figure 3 , Figure 4 , Figure 5 The cut-off mechanism 6 includes a drive assembly 61 and a cut-off block 62. The cut-off block 62 is connected to the drive assembly 61, which drives the cut-off block 62 to the point where the heat sink housing 53 communicates with at least one of the first channel 541 and / or the second channel 542, so as to cut off the transmission of heat dissipation airflow.

[0068] During operation, when the operating temperature of the photovoltaic access mechanism 4 is lower than the preset temperature and the operating temperature of the wind power access mechanism 3 is higher than the preset temperature, the drive component 61 drives the cut-off block 62 to move to the connection between the heat dissipation shell 53 and the first channel 541 to close the first channel 541, thereby reducing the delivery of heat dissipation airflow to the sub-chamber where the photovoltaic access mechanism 4 is located, and allowing more heat dissipation airflow to flow to the sub-chamber where the wind power access mechanism 3 is located and the sub-chamber where the energy storage mechanism 2 is located.

[0069] When the operating temperature of the wind power access mechanism 3 is lower than the preset temperature, and the operating temperature of the photovoltaic access mechanism 4 is higher than the preset temperature, the drive component 61 drives the stop block 62 to move to the connection point between the heat dissipation housing 53 and the second channel 542, thereby closing the second channel 542. This reduces the flow of heat dissipation airflow to the sub-chamber where the wind power access mechanism 3 is located, and allows more heat dissipation airflow to flow to the sub-chamber where the photovoltaic access mechanism 4 and the energy storage mechanism 2 are located. When the operating temperatures of both the photovoltaic access mechanism 4 and the wind power access mechanism 3 are lower than the preset temperature, the drive component 61 can also drive the stop block 62 to simultaneously close the first channel 541 and the second channel 542, so that the heat dissipation airflow is preferentially delivered to the sub-chamber where the energy storage mechanism 2 is located via the third channel 543. This configuration allows for targeted adjustment of the flow direction of the heat dissipation airflow according to the heat dissipation requirements of different mechanisms under different operating conditions.

[0070] It is understandable that the cutoff block 62 can not only move to completely close the connection between the first channel 541 and / or the second channel 542 to cut off the heat dissipation airflow, but also move to partially block the connection between the first channel 541 and / or the second channel 542 to adjust the flow cross-sectional area of ​​the corresponding channel, thereby adjusting the flow rate of the heat dissipation airflow entering the first channel 541 and the second channel 542. Through the above configuration, when the power consumption of the heat dissipation mechanism 5 is basically the same, the heat dissipation airflow can be distributed among different channels, so that the area of ​​the mechanism with higher heat dissipation demand receives more heat dissipation airflow, and the area of ​​the mechanism with lower heat dissipation demand receives less heat dissipation airflow. This is beneficial to improving the flexibility and targeting of the heat dissipation airflow distribution and improving energy utilization efficiency.

[0071] In some embodiments of this disclosure, see Figure 2 , Figure 3 , Figure 4 , Figure 5 The drive assembly 61 includes a drive motor 611, a drive screw 612, a first gear 613, and a second gear 614. The drive screw 612 is slidably connected to the heat sink 53, and the axial direction of the drive screw 612 is the same as the first direction. The first gear 613 has a motion hole 6131, and the drive screw 612 is disposed in the motion hole 6131 of the first gear 613 and threadedly connected to the side wall of the motion hole 6131. ​​The second gear 614 is rotatably connected to the heat sink 53 and meshes with the first gear 613. The drive motor 611 is used to drive the second gear 614 to rotate.

[0072] During operation, the drive motor 611 outputs driving force to rotate the second gear 614, which in turn drives the first gear 613, which meshes with it, to rotate. Since the drive screw 612 is threadedly connected to the side wall of the movement hole 6131 of the first gear 613, and is slidably connected to the heat sink 53, the drive screw 612 generates linear motion along the first direction when the first gear 613 rotates. As the drive screw 612 moves, it can further drive the stop block 62 to move synchronously, so that the stop block 62 moves to the point where the heat sink 53 connects with the first channel 541 and / or the second channel 542, or moves away from the corresponding connection point, thereby adjusting the on / off state of the first channel 541 and the second channel 542. By converting the rotational motion of the drive motor 611 into linear motion of the drive screw 612 along the first direction, the stability and adjustment accuracy of the stop block 62's movement are improved, thus facilitating more accurate control of the heat dissipation airflow direction.

[0073] In some embodiments of this disclosure, see Figure 1 , Figure 2The power distribution access device also includes a diversion mechanism 8. The diversion mechanism 8 includes a diversion housing 81, which is connected to the power distribution housing 1 and located at the inlet end of the heat dissipation mechanism 5 along the first direction. Along the first direction, multiple second air inlets 811 are provided on both sides of the diversion housing 81, and the multiple second air inlets 811 are connected to the first air inlet 531.

[0074] During operation, outside air can enter the intake housing 81 through multiple second air inlets 811 on both sides of the intake housing 81, then flow from the intake housing 81 to the first air inlet 531, and further into the heat dissipation housing 53 for the heat dissipation mechanism 5 to provide airflow and ventilation. Because the multiple second air inlets 811 are located on both sides of the intake housing 81, compared to a direct upward air inlet, rainwater is less likely to directly enter the intake housing 81 during rain, thus reducing the possibility of rainwater entering the distribution housing 1. This design helps protect the energy storage mechanism 2, the wind power access mechanism 3, and the photovoltaic access mechanism 4, reducing the adverse effects of rainwater intrusion on the operational stability and service life of each mechanism.

[0075] In some embodiments of this disclosure, see Figure 1 , Figure 2 The power distribution access device also includes a drying mechanism 9. The drying mechanism 9 is located inside the cavity of the intake housing 81. During operation, the air entering the intake housing 81 through the second air inlet 811 is first processed by the drying mechanism 9, then flows to the first air inlet 531 and enters the heat dissipation housing 53, and then the heat dissipation mechanism 5 delivers the air to each sub-chamber.

[0076] By installing a drying mechanism 9 inside the inlet housing 81, the air entering the distribution housing 1 can be dried, thereby reducing air humidity and minimizing the entry of humid air into the distribution housing 1. This helps protect the energy storage mechanism 2, the wind power access mechanism 3, and the photovoltaic access mechanism 4, reduces the adverse effects of a humid environment on these mechanisms, and improves the stability and reliability of the power distribution access device.

[0077] Furthermore, in some embodiments of this disclosure, the drying mechanism 9 can be a desiccant, and the inlet housing 81 includes a top cover 812, which is openable to facilitate the periodic placement or replacement of the desiccant into the inlet housing 81, thereby drying the air entering the inlet housing 81. It is understood that the drying mechanism 9 can also be other structures capable of drying or dehumidifying air, which will not be elaborated upon in this application.

[0078] In summary, this application provides an integrated wind power, photovoltaic, and energy storage power distribution access device. By integrating an energy storage mechanism 2, a wind power access mechanism 3, and a photovoltaic access mechanism 4 within the same power distribution housing 1, it achieves centralized access of wind and photovoltaic power to the energy storage mechanism 2, which then distributes the power to the external power distribution side. This reduces the overall footprint, improves space utilization, and facilitates unified wiring, centralized maintenance, and unified management. The power distribution housing 1 is divided into multiple sub-chambers by partitions 11. The wind power access mechanism 3, the photovoltaic access mechanism 4, the energy storage mechanism 2, and the heat dissipation mechanism 5 are respectively located in different sub-chambers, achieving zoned layout, facilitating individual maintenance, and reducing mutual interference between different functional areas. Furthermore, the cooling airflow generated by the heat dissipation mechanism 5 can be delivered to the wind power access area, the photovoltaic access area, and the energy storage area through different channels. The channel length corresponding to the energy storage area is shorter, allowing the energy storage mechanism 2 to obtain more cooling airflow, thus prioritizing the heat dissipation needs of the energy storage mechanism 2 during continuous operation. Meanwhile, the power distribution access device is also equipped with a cut-off mechanism 6, a temperature sensor 7, and a drive component 61. Based on the temperature changes of the wind power access mechanism 3 and the photovoltaic access mechanism 4 under different operating conditions, it can selectively close, open, or regulate the flow of different channels to achieve directional distribution and fine control of heat dissipation airflow, thereby improving the heat dissipation targeting and energy utilization efficiency under the same or lower power consumption conditions.

[0079] Furthermore, the power distribution access device may also include a diversion mechanism 8 and a drying mechanism 9. The diversion mechanism 8 guides outside air through a second side-mounted air inlet 811 to reduce the possibility of rainwater directly entering the power distribution housing 1. The drying mechanism 9 dries the air entering the device, thereby reducing the adverse effects of humid air or rainwater on the energy storage mechanism 2, the wind power access mechanism 3, and the photovoltaic access mechanism 4, and improving the overall operational stability, reliability, and service life.
